It's effect on those I love. The events that lead up to that point are very personal and so are my reasons; but it is fair to say that the passion Christians feel toward spreading Christianity is equal to my passion for stopping it. I don't think Christians are "bad people" or anything, but I believe Christianity, as a religion, spreads damaging ideologies. I'm sure you have read the complaints of Bertrand Russell, Ayn Rand, David Hume, Thomas Paine and Friedrich Nietzsche. My complaints are much the same as theirs. It does no good, however, for us to try to convert each other. Once someone becomes a Christian, I do very little to try to counter that; I simply try to "save" non-Christians from being converted by teaching them the approaches and arguments Christians use; their methods and techniques. Again, once you've established yourself in a religion, I won't try to convince you that you are wrong. I will only put my world view out there for you to see. If you like it more, then you'll take the rest of the steps.
No. My parents and grandparents rarely ever talked about hell. In fact, most of their focus was on Love. My Grandfather, well, he is a Southern Baptist Preacher... so I'll let you figure that one out.
He is a great man though.
Also, let me say, I have two of the most loving parents in all the world. There isn't anything that they wouldn't do for me and we are the best of friends. There is no animosity there.
